Originally a physical chemist and later a science journalist, he moved to London in 1967, where he worked in theoretical biology at the Galton Laboratory, making three important contributions: first, rederiving W.D.

[3] In 1947 he married Julia Madigan, but their relationship was contentious as George was a strong atheist while his wife was a practicing Roman Catholic.

In 1955 and 1956, he published two papers in the journal Science criticizing the pseudoscientific claims of extrasensory perception.

[5][6] Continuing with science journalism, Price tried to write a book titled No Easy Way about the United States' Cold War with the Soviet Union and the People's Republic of China, but complained that "the world kept changing faster than I could write about it", and so the book was never finished.

Later he turned away from Biblical scholarship and instead dedicated his life to community work, helping the needy of North London.

He also pioneered the application of game theory to evolutionary biology, in a co-authored 1973 paper with John Maynard Smith.

The reason for this is that each of these relatives' genetic makeup contains (on average in the case of siblings) 50% of the genes that are found in the original organism.

So if the original organism dies as a result of an altruistic act it can still manage to propagate its full genetic heritage as long as two or more of these close relatives are saved.

As part of an attempt to prove his theory right or wrong, he began showing an ever-increasing amount (in both quality and quantity) of random kindness to complete strangers.

[15] Possibly due to the long-term complications of his thyroid treatment,[1] Price committed suicide on January 6, 1975, by cutting his carotid artery with a pair of nail scissors.

[17] Price's contributions were largely overlooked for 20 years; he had worked in theoretical biology for only a short time and was not very thorough in publishing papers.

[19] On 29 March 2016, Farnworth's play Calculating Kindness opened for a sold-out three-week run at the Camden People's Theatre.
